Hello,
In FME Form, I am trying to generate a line from 3 parameters:
- lon/lat (WGS 84)
- length
- geographic orientation (from geographic north, in degrees)
I have tried several ways to build this line (2DDirectionExtender, VertexCreator + Offsetter (tested polar coordinates or spherical coordinates), VertexCreator + Rotator)
Always the same result, when I measure the angle from geographic north, there is a difference for instance, with my input:
- lon/lat : -4.49027778, 48.02000000
- length : 0.002
- orientation : 100.478°
In both methods, FME gives me this result:

When I calculate the bearing from start point to generated end point, it gives me the same result 105.411° (same with online bearing calculators using coords)
Any idea on what could be wrong?
Thank you
